For emergencies dial 999. This may not work. Simply because our telcos do not to cover Ubin fully and and you get roaming coverage from Malaysian telcos instead.
You then get a ‘free’ spam sms message from Starhub.

Although I haven’t tried. Here are the emergency numbers provided by NPark to call.

You can call Van operators – Mr. Moh at +65-9731-7629/ +659084-8827 or Tien Song at +65-93468017 to drive you back to the jetty. Speak to them in Mandarin or slowly in English.
Its probably best to bring a whistle and avoid exploring remote areas alone by yourself.
Familiarize yourselves with the location of NParks public toilets and bring an emergency toilet roll. Once I had to dive into the quarry lake to do my business. My scout master warned not to use leaves to wipe bottoms as you may get allergic rash.
